“…It is clearly observed that the compressive stress increases from 1.7 to 2.2 GPa as the arc current is increased from 20 to 80 A, The increase of compresive stress in composite SiN x /DLC film is due to the change in the film microstructure. Holmberg et al [29] reported that the compressive stresses in vacuumdeposited coating are related to the microstructure and thus sensitive to the deposition condition.…”

Composite SiN x /DLC films were deposited on Si substrate by RF magnetron sputtering of silicon nitride (Si 3 N 4 ) target simultaneously with filtered cathode arc (FCA) of graphite. The RF power was fixed at 100 W whereas the arc currents of FCA were 20, 40, 60 and 80 A. The effects of arc current on the structure, surface roughness, density and mechanical properties of SiN x /DLC films were investigated. The results show that the arc current in the studied range has effect on the structure, surface roughness, density and mechanical properties of composite SiN x /DLC films. The composite SiN x /DLC films show the sp 3 content between 53.5% and 66.7%, density between 2.54 and 2.98 g/cm 3 , stress between 1.7 and 2.2 GPa, and hardness between 35 and 51 GPa. Furthermore, it was found that the density, stress and hardness correlate linearly with the sp 3 content for composite SiN x /DLC films.

“…Different contributions can affect the fatigue resistance of PVD and CVD coated components. Compressive residual stresses introduced by the deposition process often produce a beneficial effect on the fatigue behavior of coated components [17,18,32,33], although their advantage can be reduced by the microstructural modifications induced in the substrate material by the high temperatures typical of these processes [34], especially when light alloys are considered. The fatigue characteristics of coated aluminium and titanium alloys deserve indeed increased attention, since the positive effects which are often found on harder substrates must not be taken for granted on these materials [34][35][36][37][38][39][40][41][42].…”

Abstract:In the present manuscript, an extended review on the state of the art on the experimental and numerical characterization of the fatigue behavior of Physically Vapor Deposited (PVD) and Chemically Vapor Deposited (CVD) thin hard coatings is presented. The current application and development fields of PVD and CVD treatments are analysed, focusing on the advantages granted by the adoption of these coatings for corrosion protection on various materials and components. The most recent experimental research results related to the fatigue behavior of PVD and CVD coated specimens are reported. Fatigue strength values are presented for various coating processes on different substrates, including hard steel as well as aluminium and titanium light alloys. Corrosion fatigue effects on coated specimens are presented where available, in order to evaluate the coating effectiveness in aggressive environments. An overview on the current state of development of theoretical and numerical models for the characterization of coated components and for the maximum number of cycles to failure is proposed to the reader.

“…[13][14][15] The residual stress state of a coated sample depends on the substrate characteristics, coating materials and processing parameters. 12,[16][17][18][19] Surface roughness could also affect the stress state. 20) Regarding RS influence on the service behavior of coated systems, data reported in the literature indicate that high compressive RS can improve the wear resistance of these systems, [21][22][23][24] however, higher compressive stresses also increase the possibility of film detachment during system duty in tribological applications.…”

The aim of this work is to study residual stresses (RS) in PVD TiN and CrN coated ADI substrates with different nodule counts, austempering temperatures and surface finishing methods (grinding and polishing). Coatings were applied by arc ion plating using an industrial reactor and different sets of processing parameters. Residual stress measurements were performed by x-ray diffraction using the sin 2 ψ method along two principal axes on the samples surface (parallel and perpendicular to the substrate abrasion direction). The film thickness, hardness and adhesion of each coated sample were also evaluated.The results obtained indicate that RS in TiN and CrN coated samples are compressive irrespective of the different substrates, surface finishing methods and processing parameters utilized. The parallel and perpendicular RS do not vary significantly, indicating a rotationally symmetric biaxial stress state. The RS of the coated samples are not influenced by the different substrate characteristics regarding microstructure, hardness and surface roughness. The microhardness and RS of TiN and CrN coated samples increase with film thickness. The increase in substrate temperature together with the decrease in the values of BIAS voltage, arc current and chamber pressure lead to microhardness and RS reduction. Grinding produces surface hardening and reduction of the compressive RS in the substrates, but causes no variations in the RS of the TiN and CrN coated samples. The adhesion strength quality of TiN and CrN coatings to ADI substrates can be related to indices ranging from HF1 to HF2.
